For over five decades, Norstan has served the industry by manufacturing specialized precision electrical contacts and stampings in short and long production runs. Our products are expertly produced per our customer’s specifications and made from highly conductive metals, such as brass, copper, gold, palladium, platinum, and silver. In addition to our precision stamping and welding capabilities, we also leverage furnace brazing when needed for a custom metal part
Furnace brazing is a metalworking process that employs heat and a dissimilar metal filler material to join two metal pieces together. Compared to soldering, which also uses filler material to bind parts together, the process relies on brazing alloys for higher melting points. Additionally, it serves as a more cost-effective method of producing strong and durable bonds in high volumes.
Depending on the specifications of the part and project, industry professionals may use a variety of different furnaces to provide the necessary heat for the brazing process, such as vacuum, continuous, controlled atmosphere, or reduced atmosphere furnaces. At Norstan, we utilize both controlled atmosphere and continuous (also known as mesh belt) furnaces for our furnace brazing operations.
Brazing operations typically involve the following steps:
Although furnace brazing may not be the right choice for every application, it does offer several advantages over other metal-joining methods, such as:
Furnace brazing is suitable for yielding a strong bond in high volumes at competitive prices. At Norstan, our furnace brazing capabilities allow us to produce high-quality precision electrical contacts and custom metal products for use in a wide range of electromechanical devices.
